基因信息

human ... H2AFZ(3015)

一般描述

H2A.Z,也称H2AFZ,是组蛋白H2A的一种变体,从酵母到人类细胞高度保守。像其他组蛋白变体一样,H2A.Z是由一种独特的基因编码的,产生一种略微不同的H2A类型,具有特殊的功能。H2A.Z通过稳定核小体内的组蛋白八聚体参与染色质压实。它通过创造一个更容易转录的染色质开放区域来促进基因表达。H2A.Z在整个基因组中非随机分布,主要针对中心外异染色质,但排除在无活性X染色体和细胞核外。H2A.Z与常染色质和兼性异染色质有关。DNA甲基化可以通过排除H2A.Z影响染色质结构和基因沉默效应,同样,H2A.Z也可以保护基因免受DNA甲基化的影响。因此,H2A.Z在调节异染色质沉默中起作用,并参与转录控制。

特异性

识别组蛋白H2A.Z
预期具有广泛的反应性

免疫原

与人组蛋白H2A.Z的近C末端区域相对应的KLH偶联的线性肽。

应用

染色质免疫沉淀(ChIP):该抗体的代表性批次(每次反应1μg)用于使用HeLa和K562细胞的染色质进行ChIP。

ChIP-seq:该抗体的代表性批次(每次反应0.5 μg)用于免疫沉淀K562染色质以进行ChIP-seq分析。

蛋白印迹分析:该抗体的代表性批次按1:20 00稀释后在酸提取HeLa细胞裂解液中检测到组蛋白H2A.Z。

免疫细胞化学: 代表性批次的1:500稀释液在HeLa细胞中检测到组蛋白H2A.Z。
该抗组蛋白 H2A.Z 抗体(C-端)经验证可用于蛋白质印迹、染色质免疫沉淀(ChIP)、ChIP-seq、免疫细胞化学和ELISA中组蛋白 H2A.Z(C-端)的检测。

质量

使用重组组蛋白通过蛋白质印迹进行了评估。

蛋白质印迹分析:该抗体的1.5 µg/mL稀释液检测到重组组蛋白H2A.Z,但未检测到组蛋白H1、H2A、H2A.X、H3或H4。

目标描述

观测值〜16 kDa

外形

亲和纯化兔多克隆抗体,溶于含0.05%叠氮化物和0.05% ProClin 300的PBS。

Somatic inactivation of p53 (TP53) mainly occurs as missense mutations that lead to the acquisition of neomorphic mutant protein forms. p53 mutants have been postulated to exert gain-of-function (GOF) effects, including promotion of metastasis and drug tolerance, which generally contribute

Rapid removal of histone H2A.Z from neuronal chromatin is a key step in learning-induced gene expression and memory formation, but mechanisms underlying learning-induced H2A.Z removal are unclear. Anp32e was recently identified as an H2A.Z-specific histone chaperone that removes H2A.Z from

Creating long-lasting memories requires learning-induced changes in gene expression, which are impacted by epigenetic modifications of DNA and associated histone proteins. Post-translational modifications (PTMs) of histones are key regulators of transcription, with different PTMs producing unique effects on gene activity

Memory formation is a protracted process that initially involves the hippocampus and becomes increasingly dependent on the cortex over time, but the mechanisms of this transfer are unclear. We recently showed that hippocampal depletion of the histone variant H2A.Z enhances

Emerging evidence suggests that histone variants are novel epigenetic regulators of memory, whereby histone H2A.Z suppresses fear memory. However, it is not clear if altered fear memory can also modify risk for PTSD, and whether these effects differ in males
